Energy performance contract penalties: calculation, caps, exemptions

[/WIDGET:featured-image]

The penalty paid by the operator does not take a single kWh off your Décret tertiaire trajectory (France's tertiary decree on energy savings in commercial buildings). The target of -40% final energy consumption in 2030 remains with the owner and, where applicable, the tenant^{[1][1]RegulationLégifrance, “Decree No. 2019-771 of 23 July 2019 on obligations to reduce final energy consumption in commercial buildings” (Décret tertiaire)See in sources ↓}. The real risk? An amount calculated on a fragile baseline or on unreliable building meters. Before opening the energy performance contract penalties file, the building owner keeps one rule in mind: a penalty is only worth what its measurement is worth. Calculation, cap, exemptions: here is how to test the promised energy savings.

What an EPC penalty sanctions

A results-based contract built on a baseline

The energy performance contract (EPC, called CPE in France) commits an operator to a measured result, not to means. Promoted by the Grenelle I law, adopted in the wake of the Grenelle environment forum (Law No. 2009-967, article 5)^{[2][2]RegulationLégifrance, “Law No. 2009-967 of 3 August 2009 on planning for the implementation of the Grenelle environment forum” (Grenelle I law), article 5See in sources ↓}, the EPC is a results-based contract. Works, services or a global contract must deliver verifiable energy savings. Failing that, a financial clause applies.

Three pillars hold the whole thing together. The baseline freezes the starting consumption. The guaranteed target sets the energy performance to be achieved. The penalty compensates the building owner if that target is not met. The text published on Légifrance sets the principle. The clause drafted between the parties sets its real scope.

Performance guarantee, penalty, penalty clause: three notions not to confuse

The guarantee is the commitment: a consumption level the operator undertakes to meet. The penalty is its financial counterpart, triggered by the gap. The EPC penalty clause (clause pénale) falls under general contract law: article 1231-5 of the French Civil Code governs any lump sum set by contractual agreement^{[3][3]RegulationLégifrance, “Civil Code”, article 1231-5See in sources ↓}. A poorly calibrated clause in the contract is therefore never final.

Did you know? A judge may, even on their own initiative, reduce or increase a penalty that is manifestly excessive or derisory^{[3][3]RegulationLégifrance, “Civil Code”, article 1231-5See in sources ↓}. An energy performance penalty set too low to worry the operator is therefore not set in stone.

What the order of 24 July 2020 requires of the contract

Eleven years after the Grenelle law, the official reference text is the order (arrêté) of 24 July 2020 on energy performance contracts, available on legifrance.gouv.fr^{[4][4]RegulationLégifrance, “Order of 24 July 2020 on energy performance contracts” (NOR TRER2016315A), Official Journal (JORF) of 31 July 2020, article 2See in sources ↓}. Issued under the French Environment Code, it defines the EPC and requires a penalty “based on the consumption gap measured against the contractual commitment” (article 2)^{[4][4]RegulationLégifrance, “Order of 24 July 2020 on energy performance contracts” (NOR TRER2016315A), Official Journal (JORF) of 31 July 2020, article 2See in sources ↓}. The written annual report, for its part, is set by the contract and model clauses, not by the order. For buyers subject to the Public Procurement Code, it ties in with the global performance contract (marché global de performance, article L2171-3)^{[5][5]RegulationLégifrance, “Public Procurement Code”, article L2171-3See in sources ↓}.

What the order leaves unsettled weighs more. It requires a baseline corrected for external factors and allows a check by an accredited body at the request of either party (article 2)^{[4][4]RegulationLégifrance, “Order of 24 July 2020 on energy performance contracts” (NOR TRER2016315A), Official Journal (JORF) of 31 July 2020, article 2See in sources ↓}. The detailed measurement method, the weather station used and the kWh price are left to the contract. Carbon and greenhouse gases are not part of the formula, which only counts energy efficiency gains in kWh.

Services EPC, works EPC, global contract: the penalty does not cover the same thing

Each type of EPC defines what the gap can sanction. Remember that the penalty only covers the scope of the contract:

• Services EPC: the contractor guarantees a result through operations, without heavy investment.
• Works EPC: the guarantee covers heating and ventilation equipment that is replaced or added.
• Global contract: the public buyer entrusts design, works and operation to a single contractor.

On the financing side, third-party financing and the CEE premium (CEE energy-savings certificates) ease the burden on the public body without changing the type of contract or the basis of the penalty.

Penalty calculation, deductible and cap: from the consumption gap to the amount due

A penalty based on the measured gap: the definition to remember

The penalty of an energy performance contract is the sum owed by the operator when measured consumption exceeds the guaranteed target. The order of 24 July 2020, published on Légifrance, links it to the consumption gap measured against the contractual commitment^{[4][4]RegulationLégifrance, “Order of 24 July 2020 on energy performance contracts” (NOR TRER2016315A), Official Journal (JORF) of 31 July 2020, article 2See in sources ↓}. The annual report that establishes this gap, for its part, is provided for in the contract. In practice, the EPC penalty is built as a cascade: raw gap, weather correction, adjustments, deductible, cap.

The breakdown tool below walks through this cascade step by step. Enter the parameters of your own contract: the values shown are only examples.

First compare the final penalty with the line without HDD correction. If the difference between these two amounts exceeds the penalty itself, the discussion with the operator will be about the method before it is about the figure.

Measuring the raw gap between measured consumption and the guaranteed target

Before any calculation, settle what “measured” means. Distribution network operator reading, supplier invoice or BMS sub-meter: the three sources rarely give the same energy total over the same period.

Does your contract specify which data is authoritative, over which period and for which uses? A measurement that includes a server room added after the baseline inflates the gap without saying anything about performance.

Correcting the gap for weather variations with HDD

A mild winter hides a drift. Conversely, a harsh winter can manufacture a penalty on a properly operated building. Correction by heating degree days (HDD, called DJU in France) brings heating consumption back to the weather conditions of the baseline year, as the IPMVP protocol allows.

Three parameters must be set down in writing: the weather station, the base temperature and the baseline year. Without them, energy performance is negotiated every year instead of being measured.

Adjusting the baseline for occupancy, operating hours and floor area

Occupancy that drops, extended operating hours, an extra floor leased: the building's situation changes. The baseline has to follow, and the rule is simple: an adjustment that is not written down does not exist.

The contract names who calculates the adjustment, on which data and from which threshold it applies. On a multi-tenant site, implementation quickly stalls if nobody is in charge of passing on the occupancy data.

Converting the gap into euros: which kWh price to use?

Two approaches clash. A contractual price fixed at signature makes the penalty predictable. The price actually invoiced follows the energy market: the amount moves while the physical gap does not.

For the owner, the question bears on the balance of the investment. A price indexed on the invoice exposes both parties to volatility, whereas the contract was meant to measure kWh savings.

Proportional or flat-rate penalty: what the calculation method changes

The calculation method decides who carries the exposure. A proportional penalty follows the gap, whereas the Groupe Action Logement standard clause sets a flat rate triggered by a finding^{[6][6]Studies and reportsLa clause verte, “Groupe Action Logement standard clause”, energy performance penaltiesSee in sources ↓}.

The flat rate per unit exposes the contractor less to the energy market, but it disconnects the penalty from actual energy performance: each type of EPC has its own trade-off.

Annual cap or cap over the term: what the operator really limits

A penalty cap is drafted in one of two ways: a percentage of the operator's fee or a fixed amount. It applies per year or over the whole term of the contract. The latter limits exposure far more over a long period.

The decisive question: what happens to the gap above the cap? If it disappears, the guarantee stops working precisely when the drift becomes serious.

Does too wide a deductible empty the guarantee?

The deductible (or tolerance band) absorbs small gaps without a penalty. Combined with measurement uncertainty, it can neutralize the commitment: missing the EPC target by a few points is then never invoiced.

Always read the two figures together. A performance guarantee whose deductible exceeds the effort asked of the operator no longer guarantees much. Meeting it is a foregone conclusion.

Offsetting between years: when overperformance wipes out a penalty

A single annual report does not tell the whole story. With a cumulative report or a carry-forward clause, a good year can wipe out a bad one: one winter's overperformance offsets the next one's drift.

The mechanism is defensible over the term of an energy performance contract. It becomes dangerous in two cases: savings due to the weather rather than to operations, and a carry-forward with no time limit.

Checking the gap and the exemptions before applying the penalty

The measurement and verification plan: what the annual report must contain

The order of 24 July 2020 requires a penalty based on the measured gap^{[4][4]RegulationLégifrance, “Order of 24 July 2020 on energy performance contracts” (NOR TRER2016315A), Official Journal (JORF) of 31 July 2020, article 2See in sources ↓}, without saying how that gap is measured or how often. The written annual report and its content are left to the energy performance contract. Without an appended measurement and verification plan, the client receives an amount and a conclusion, rarely the method that links them.

Each report must contain three elements: the IPMVP option chosen, the raw data in an appendix and the adjustment method applied. This international measurement protocol does not do the work. It sets the grammar that lets you measure the gap under IPMVP on your building.

A baseline set by the operator alone: the first weak point

In many arrangements, the operator carries out the baseline study itself. It chooses the period, the meters and the uses included. Hence a rule: the operator only guarantees what it has assessed itself. An inflated baseline makes the target easy to meet. The client discovers the bias at the first report, when the baseline is already frozen in writing.

Meters and trend logs: making the data reliable before freezing the baseline

Before freezing the baseline, check what the meters are worth. Disconnections, data gaps, duplicates and invisible drifts show up on a curve. The one below, built for the example and with no real data, combines three of them.

Several weeks without readings, then a catch-up spike: the trend log concentrates consumption on a single day and distorts the profile. Further on, a slow drift in the metering chain stays below the building management system's alarm threshold. A baseline built on a faulty meter distorts every report.

Disputing an annual report: procedure, deadlines and third-party expert

A dispute is prepared in the contract, long before the day of the disagreement. Three steps must be set out in black and white:

1. The client's access to the raw data, in a usable format.
2. Written dispute deadlines, with a start date set at the delivery of the report.
3. Recourse to a third-party expert appointed by mutual agreement, whose opinion binds both parties.

Without this framework, whether the client's right to dispute is respected depends on the operator's goodwill.

The eight questions to ask before signing or at the first report

Before signing or at the first report, eight questions are enough to know whether the penalty will hold up. Tick those your contract answers in writing, with a clause to back it up.

Each empty box signals a penalty that cannot be enforced on the day the gap appears, or a penalty either party can dispute. The lower the counter, the more room your measurement plan and the chosen IPMVP option leave for interpretation.

That leaves the exemptions the operator negotiates in the contract: each one shifts part of the risk to the owner.

Force majeure: what the contract adds to article 1218 of the Civil Code

Article 1218 of the French Civil Code covers an event beyond the debtor's control, unforeseeable when the contract was concluded and irresistible in its effects^{[7][7]RegulationLégifrance, “Civil Code”, article 1218See in sources ↓}. General contract law therefore sets three demanding conditions.

Some contracts get around them with an extended contractual list: equipment failure, strike, heatwave, supplier default. Each addition turns an operational risk into an exemption. Read this list as a hidden deductible.

Setpoints changed by the occupant or the building owner: who touched the BMS?

The director on the top floor demands 24-25 °C all year round (seen many times). The O&M contractor forces the setpoint to calm the VIP complaint, then forgets to release it. A few months later, the consumption gap is there.

Who touched the building management system? Without a time-stamped log of every operation, manual overrides included, nobody can tell. The operator blames the gap on the building owner. The client blames the operator. Responsibility gets diluted.

Unavailable data: who benefits from the measurement gap?

A meter silent for several weeks: what does the contract provide? Often an exemption for the operator for the period without data. In that arrangement, the measurement risk shifts to the owner, even when maintaining the metering chain is the contractor's job. Require a written reconstruction rule and a minimum rate of usable consumption readings.

Owner's works and out-of-scope equipment: the boundary to draw

The owner replaces an AHU or adds a chiller during the contract. Who carries the gap? It all depends on the type of contract. In a services EPC, the operator commits to operating listed equipment. In a works EPC, it is also liable for the result of its own works.

In both cases, the scope boundary is drawn equipment by equipment. A new build or an extension calls for an amendment signed by the client, never a silent adjustment.

What the penalty settles in the contract and what it leaves open, with three cases

The contractor's obligations over the term of the contract

The contractor has an obligation of result. It guarantees a level of energy savings, not an effort. It maintains the measurement plan and produces each year the written report the contract requires of it, the order merely requiring a penalty based on the measured gap^{[4][4]RegulationLégifrance, “Order of 24 July 2020 on energy performance contracts” (NOR TRER2016315A), Official Journal (JORF) of 31 July 2020, article 2See in sources ↓}. It also follows up on improvement actions until the end of the guarantee.

This report is the document on which everything hinges. Without it, no penalty can be calculated and no gap can be discussed.

The lifecycle of an EPC, milestone by milestone: who measures, who validates, who disputes

An energy performance contract runs over several years. The penalty only comes at the end of a chain of decisions. The timeline below covers its five milestones and asks the same question at each one: who measures, who validates, who disputes?

Read it in order. The baseline, the measurement plan and the implementation of the actions are decided before the first euro of penalty. When the operator measures alone at each milestone, the building owner validates what it did not see being built. The last row recalls what the penalty does not settle, even during the guarantee period.

Formal notice, repeated penalties, termination: when missing the target tips the contract over

Missing the EPC target rarely triggers the penalty straight away. The Action Logement standard clause provides for a formal notice before the flat rate^{[6][6]Studies and reportsLa clause verte, “Groupe Action Logement standard clause”, energy performance penaltiesSee in sources ↓}. The response time given to the operator then becomes a condition of validity.

Repeated gaps raise another question. How many missed reports allow termination? If the threshold is not written down, the energy performance penalty remains a line the operator provisions for every year.

Contractual liability: the penalty does not wipe out the damage

A well-drafted clause specifies that payment is made “without prejudice” to a liability claim^{[6][6]Studies and reportsLa clause verte, “Groupe Action Logement standard clause”, energy performance penaltiesSee in sources ↓}. In other words, the penalty does not wipe out the damage: the building owner keeps the right to sue for the actual damage.

That damage sometimes far exceeds the flat rate. The Action Logement standard clause makes it calculable on a 50-year loss of rent^{[6][6]Studies and reportsLa clause verte, “Groupe Action Logement standard clause”, energy performance penaltiesSee in sources ↓}. Without this wording, the contract leaves doubt as to whether the payment discharges the contractor in full.

Incentive for overperformance: the symmetry to negotiate

As a mirror of the guarantee, many contracts provide for an incentive when savings exceed the target^{[8][8]Press and announcementsLe Moniteur, “The energy performance contract: a user's guide”, V. Sablier and I. SerbanescuSee in sources ↓}. This is the symmetry to negotiate: same baseline, same adjustment method, same weather correction in both directions. The sharing keys fall under shared savings.

Décret tertiaire: a penalty collected is not a trajectory met

The Décret tertiaire requires a 40% reduction in final energy consumption by 2030 compared with a reference year^{[1][1]RegulationLégifrance, “Decree No. 2019-771 of 23 July 2019 on obligations to reduce final energy consumption in commercial buildings” (Décret tertiaire)See in sources ↓}. This obligation falls on the owner and the tenant, never on the operator. The check received does not take a single kWh off the declared trajectory.

A penalty collected is not a trajectory met. In the French commercial building sector, greenhouse gas emissions reports fall under other texts, depending on the applicable thresholds. A contract that mixes a carbon target and an energy target creates misunderstandings about what is guaranteed.

Social housing: €4,000 per unit after formal notice

The Groupe Action Logement standard clause, drafted for the CCAP (special administrative terms) of a construction contract (performance measured at the latest during the one-year defects warranty, the garantie de parfait achèvement) and not for an EPC, sets a flat rate of €4,000 per unit delivered when the target is still missed after formal notice^{[6][6]Studies and reportsLa clause verte, “Groupe Action Logement standard clause”, energy performance penaltiesSee in sources ↓}. The amount has the merit of being clear: no kWh price or gap calculation to argue about.

Its limit lies in that very simplicity. The flat rate says nothing about the real gap or the landlord's damage. The liability claim remains open and the judge will decide what the flat rate does not cover.

Local authority boiler plant: a -25% target over two years read before the penalty

The French Ministry for the Ecological Transition presents a boiler plant whose set target reaches -25% consumption over two years^{[9][9]Studies and reportsFrench Ministry for the Ecological Transition (ecologie.gouv.fr), “Energy performance contract for local authorities”, boiler plant exampleSee in sources ↓}. We read it as an illustrative example, not as a public-sector statistic.

For a public body, this contract falls under the Public Procurement Code. The public heating service continues during the works. Before reading the penalty, the local authority checks the baseline, the heating and ventilation scope and the start date of the two years.

What Foobot checks in a building's BMS when a penalty is at stake

Making meters reliable before freezing the baseline

At Foobot, BMS advisory often starts with the meters, before any discussion of the penalty. We track down disconnections, data gaps, duplicates and invisible drifts. These faults distort a measurement without triggering a single alarm.

Setting up this check happens before signing. A baseline frozen on a trend log with gaps commits the building for the whole term of the contract.

Finding the manual overrides that distort a report in the BMS trend log

In the building management system's history, manual overrides leave traces. An AHU runs continuously over a weekend. A setpoint stays stuck at 24 °C since a complaint last winter. Our Operations advisory surfaces them point by point.

Each operation found changes who the gap is attributable to. The time-stamped data shows who forced which point and since when.

Measuring savings under IPMVP with HDD correction: what the Valeo case shows

At Valeo, we measured -28.6% HVAC consumption under the IPMVP protocol, with HDD weather correction. A useful clarification: this project was not an EPC and no penalty was attached to it.

The case is worth it for its method. Applied to reliable data, the International Performance Measurement and Verification Protocol produces realized savings that a third party can audit. An EPC energy report should offer exactly that.

A view from the building owner's side, without being party to the contract

We are neither an EPC operator nor a signatory. We work on the building owner's side, without being party to the contract and without works. Our role: a second opinion on the baseline, the meters and the report. Energy and carbon savings are verified on actual trend logs, not on the word of the party who would be penalized.

Negotiating a penalty that will hold up on the day of the first report

The amount of a penalty is negotiated at signature. It is won or lost at the first report. A jointly verified baseline, reliable meters, a written HDD correction, dated adjustments and dispute deadlines: each missing point turns a solid clause into a debatable amount. A penalty is only worth what its measurement is worth. Before signing an energy performance contract or validating a report, ask your operator one single question: what raw data is the gap based on? If the answer is slow to come, have the gap checked by someone independent of the party who calculates it.

verify the gap with independent M&V

FAQ - energy performance contract penalties

How long does an energy performance contract last?

The term is set by each contract. It must cover enough annual reports to measure the gap over several seasons. Above all, check that the guarantee period matches the measurement period used.

What is the difference between an EPC and a conventional P1 P2 P3 operation contract?

A P1 P2 P3 contract (the French split between energy supply, operation and maintenance, and major repairs) pays for energy supply, operation and major maintenance, generally without a quantified commitment on consumption. The EPC is a results-based contract: the operator guarantees measured savings and bears the gap.

Can an energy performance contract be financed with CEE certificates?

Yes. CEE energy-savings certificates can finance part of the works through a CEE premium, depending on the applicable standardized measure sheets. It is sometimes combined with third-party financing. This aid changes neither the guarantee nor the penalty calculation.

Does my building need a minimum floor area for an EPC to make sense?

Relevance depends mainly on the consumption level and the quality of the available data. On a small building, the cost of measurement can absorb the expected savings. The payback period then becomes much longer.

What types of project are eligible for an EPC?

Any project aimed at improving energy performance: works on the envelope, the equipment or the controls, or even services alone. On the public side, the type of contract ranges from the services EPC to the global performance contract.
